Buy 3pcs Speaker Power Amplifier Board Protection Circuit Dual Relay Protector Support Startup Delay and DC Detection

Introduction:

 

The speaker protection board has the function of delay time (about 3 seconds) and DC protection (about 1V control voltage) .
The board circuit is simple, easy to make, and safe and reliable.

With LED display, it lights up during protection and goes out during normal work.

15A high current relay is suitable for most power amplifier boards.

Working voltage AC 12-15V, need independent power supply.

 

Tips:

 

1. Speaker protection requires independent power supply, and cannot share a winding with other circuits.

2.BTL circuit requires two sets of protection boards (one for each channel)

3. The protection board is only suitable for dual-power-supply power amplifiers, and cannot be used for single-power-supply power amplifiers.

Feature:
 

Working voltage: AC 12-15V

Dimensions: length 65mm width 40mm height 25mm

Package includes:

3 x Speaker protection board
